04:17
who are so much more popular than people down here,

even though they have the same score of attractiveness?
83

ืœืžืจื•ืช ืฉื™ืฉ ืœื”ื ืืช ืื•ืชื” ืชื•ืฆืืช ืžื•ืฉื›ื•ืช?

And the reason why is that it's not just straightforward looks that are important.

ื•ื”ืกื™ื‘ื” ืœื–ื” ื”ื™ื ืœื ืจืง ืžืจืื” ืฉื—ืฉื•ื‘.

So let me try to illustrate their findings with an example.

So if you take someone like Portia de Rossi, for example,

ืื– ืื ืืชื ืœื•ืงื—ื™ื ืžื™ืฉื”ื• ื›ืžื• ืคื•ืจืฉื™ื” ื“ื” ืจื•ืกื™, ืœื“ื•ื’ืžื”,

Nobody thinks that she's ugly, but she's not a supermodel, either.

96
308287
2386
05:10
(Laughter)
97
310697
2789
05:13
Now, I think that if you ask people how attractive they thought
98
313510
4093
ืขื›ืฉื™ื•, ืื ื™ ื—ื•ืฉื‘ืช ืฉืื ืชืฉืืœื• ืื ืฉื™ื ื›ืžื” ืžื•ืฉื›ืช ื”ื ื—ื•ืฉื‘ื™ื
05:17
Jessica Parker or Portia de Rossi were,
99

ืฉืฉืจื” ื’'ืกื™ืงื” ืคืจืงืจ ืื• ืคื•ืจืฉื™ื” ื“ื” ืจื•ืกื™ ื”ืŸ,

ื•ืืชื ืžื‘ืงืฉื™ื ืžื”ื ืœืชืช ืฆื™ื•ืŸ ื‘ื™ืŸ 1 ืœ 5,
05:22
I reckon that they'd average out to have roughly the same score.
101
322491

ืื ื™ ืžื ื™ื—ื” ืฉื‘ืžืžื•ืฆืข ื™ื”ื™ื” ืœื”ืŸ ืื•ืชื• ืฆื™ื•ืŸ.
05:25
But the way that people would vote would be very different.
102
325535

ืื‘ืœ ื”ื“ืจืš ื‘ื” ืื ืฉื™ื ื™ืฆื‘ื™ืขื• ืชื”ื™ื” ืฉื•ื ื”.

05:28
So Portia's scores would all be clustered around the four
103
328323
2702
ืžืคื ื™ ืฉื›ื•ืœื ืžืกื›ื™ืžื™ื ืฉื”ื™ื ืžืžืฉ ื™ืคื”.
05:31
because everybody agrees that she's very beautiful,

ื‘ืขื•ื“ ืฉืฉืจื” ื’'ืกื™ืงื” ืคืจืงืจ ืœื’ืžืจื™ ืžื—ื•ืœืงืช ื‘ื“ืขื•ืช.
05:33
whereas Sarah Jessica Parker completely divides opinion.
105
333504
2714
ื™ื”ื™ื” ืžื ืขื“ ื’ื“ื•ืœ ื‘ืชื•ืฆืื” ืฉืœื”.
05:36
There'd be a huge spread in her scores.
106
336242
1976
05:38
And actually it's this spread that counts.
107
338242
2349
ื•ืœืžืขืฉื” ื–ื” ื”ืžื ืขื“ ื”ื–ื” ืฉืžืฉื ื”.
05:40
It's this spread that makes you more popular

ื–ื” ื”ืžื ืขื“ ื”ื–ื” ืฉืขื•ืฉื” ืืชื›ื ื™ื•ืชืจ ืคื•ืคื•ืœืจื™ื™ื

342865
2176
ื‘ืืชืจื™ ื”ื›ืจื•ื™ื•ืช ื‘ืจืฉืช.
05:45
So what that means then
110
345065
1188
ืื– ืžื” ืฉื–ื” ืื•ืžืจ
05:46
is that if some people think that you're attractive,
111
346277
2605
ื–ื” ืฉืื ื—ืœืง ืžื”ืื ืฉื™ื ื—ื•ืฉื‘ื™ื ืฉืืชื ืžื•ืฉื›ื™ื,

you're actually better off

348906
1861
ื™ื•ืชืจ ื˜ื•ื‘ ืœื›ื ืœืžืขืฉื”
05:50
having some other people think that you're a massive minger.
113
350791

ืฉืื ืฉื™ื ืื—ืจื™ื ื—ื•ืฉื‘ื™ื ืฉืืชื ืžืžืฉ ืžื›ื•ืขืจื™ื.
05:55
That's much better than everybody just thinking
114
355935

ื–ื” ื”ืจื‘ื” ื™ื•ืชืจ ื˜ื•ื‘ ืžืฉื›ื•ืœื ืจืง ื™ื—ืฉื‘ื•

ืฉืืชื ื”ื‘ื—ื•ืจื” ื”ื ื—ืžื“ื” ืžืขื‘ืจ ืœืคื™ื ื”.

06:00
Now, I think this begins to make a bit more sense
116
360260
2325
06:02
when you think in terms of the people who are sending these messages.
117
362609
3270
ื›ืฉืืชื ื—ื•ืฉื‘ื™ื ื‘ืžื•ื ื—ื™ื ืฉืœ ื”ืื ืฉื™ื ืฉืฉื•ืœื—ื™ื ืืช ื”ื”ื•ื“ืขื•ืช.
06:05
So let's say that you think somebody's attractive,
118
365903
2358
ืื– ื‘ื•ืื• ื ื’ื™ื“ ืฉืืชื ื—ื•ืฉื‘ื™ื ืฉืžื™ืฉื”ื• ืžื•ืฉืš,

06:08
but you suspect that other people won't necessarily be that interested.
119
368285
3965
ื–ื” ืื•ืžืจ ืฉื™ืฉ ืคื—ื•ืช ืชื—ืจื•ืช ื‘ืฉื‘ื™ืœื›ื
06:12
That means there's less competition for you
120
372274
2245
06:14
and it's an extra incentive for you to get in touch.
121
374543
2782
ื•ื–ื” ืชืžืจื™ืฅ ื ื•ืกืฃ ื‘ืฉื‘ื™ืœื›ื ืœื™ืฆื•ืจ ืงืฉืจ.

Whereas compare that to if you think somebody is attractive
122
377349
2785
ืื‘ืœ ืืชื ื—ื•ืฉื“ื™ื ืฉื›ื•ืœื ื™ื—ืฉื‘ื• ืฉื”ื•ื ืžื•ืฉืš.
06:20
but you suspect that everybody is going to think they're attractive.
123
380158
3217
06:23
Well, why would you bother humiliating yourself, let's be honest?
124
383399
3205
ื•ื‘ื›ืŸ, ืœืžื” ืœื˜ืจื•ื— ืœื”ืฉืคื™ืœ ืืช ืขืฆืžื›ื, ื‘ื•ืื• ื ื”ื™ื™ื” ื›ื ื™ื?

06:29
Because when people choose the pictures that they use on an online dating website,
126
389494

they often try to minimize the things

that you start dating when you're 15

that you could potentially date across your lifetime,

and equally, you can't go back and change your mind.
171

1599
ืœืคื™ ื”ื ืกื™ื•ืŸ ืฉืœื™ ืœืคื—ื•ืช,

you should just reject everybody as serious marriage potential.

08:55
(Laughter)
178
535339

(ืฆื—ื•ืง)
08:57
And then, you should pick the next person that comes along
179
537513

ื•ืื–, ืืชื ืฆืจื™ื›ื™ื ืœื‘ื—ื•ืจ ืืช ื”ืื“ื ื”ื‘ื ืฉืžื’ื™ืข

09:04
So here's the example.
181
544154
1421
ืื– ื”ื ื” ื”ื“ื•ื’ืžื”.
09:05
Now if you do this, it can be mathematically proven, in fact,

Now unfortunately, I have to tell you that this method does come with some risks.

ืื ื™ ื—ื•ืฉืฉืช ืฉืืฃ ืื—ื“ ืœื ืžื’ื™ืข

I'm afraid no one else comes along

so you have to go on rejecting everyone and die alone.

12:26
But this didn't stop a psychologist, John Gottman, who did exactly that.
251
746266
6183
12:32
Gottman observed hundreds of couples having a conversation

12:40
So he recorded what was said in the conversation,

ืื– ื”ื•ื ื”ืงืœื™ื˜ ืžื” ืฉื ืืžืจ ื‘ืฉื™ื—ื”,

ืฉื‘ืžืงืจื” ื”ื™ื ืœื’ืžืจื™ ื›ืŸ.

But what Gottman and his team found

ืื‘ืœ ืžื” ืฉื’ื•ื˜ืžืŸ ื•ื”ืฆื•ื•ืช ืฉืœื• ืžืฆืื•

13:06
was how positive or negative each partner was being in the conversation.
263
786567
4623
13:11
Now, couples that were very low-risk
264
791214
2330
ืขื›ืฉื™ื•, ื–ื•ื’ื•ืช ืฉื”ื™ื• ื‘ืกื™ื›ื•ืŸ ื ืžื•ืš
13:13
scored a lot more positive points on Gottman's scale than negative.

13:17
Whereas bad relationships,
266
797861
2541
ื‘ืขื•ื“ ื™ื—ืกื™ื ื’ืจื•ืขื™ื,
13:20
by which I mean, probably going to get divorced,
267

ื•ื‘ื–ื” ืื ื™ ืžืชื›ื•ื•ื ืช, ืฉื›ื ืจืื” ื™ืชื’ืจืฉื•,

13:23
they found themselves getting into a spiral of negativity.
268
803197
4357
13:27
Now just by using these very simple ideas,
269
807578
2260
ืขื›ืฉื™ื• ืจืง ื‘ืฉื™ืžื•ืฉ ื‘ืจืขื™ื•ื ื•ืช ื”ืคืฉื•ื˜ื™ื ื”ืืœื”,
13:29
Gottman and his group were able to predict
270
809862

ื’ื•ื˜ืžืŸ ื•ื”ืฆื•ื•ืช ืฉืœื• ื”ื™ื• ืžืกื•ื’ืœื™ื ืœื—ื–ื•ืช

ืื ื–ื•ื’ ื ืชื•ืŸ ื™ืชื’ืจืฉ

with a 90 percent accuracy.

13:38
But it wasn't until he teamed up with a mathematician, James Murray,
273
818005
3289
13:41
that they really started to understand
274
821318
1891
ืฉื”ื ื”ืชื—ื™ืœื• ื‘ืืžืช ืœื”ื‘ื™ืŸ
13:43
what causes these negativity spirals and how they occur.
275

ืžื” ื’ื•ืจื ืœืกืคื™ืจืœื•ืช ื”ืฉืœื™ืœื™ื•ืช ื”ืืœื• ื•ืื™ืš ื”ืŸ ืงื•ืจื•ืช.
13:47
And the results that they found,
276
827751
1533
ื•ื”ืชื•ืฆืื•ืช ืฉื”ื ืžืฆืื•
13:49
I think, are just incredibly impressively simple and interesting.
277

13:53
So these equations predict how the wife or husband is going to respond
278
833981
4563
ืื– ื”ืžืฉื•ื•ืื•ืช ื”ืืœื•, ื”ืŸ ื—ื•ื–ื•ืช ืื™ืš ื”ืื™ืฉื” ื•ื”ื‘ืขืœ ื™ื’ื™ื‘ื•

14:00
how positive or negative they're going to be.
280
840480
2133
14:02
And these equations depend on
281
842637
1385
ื•ื”ืžืฉื•ื•ืื•ืช ื”ืืœื•, ื”ืŸ ืชืœื•ื™ื•ืช

14:04
the mood of the person when they're on their own,
282
844046
2306
14:06
the mood of the person when they're with their partner,
283
846376
2614
ืžืฆื‘ ื”ืจื•ื— ืฉืœ ื”ืื“ื ื›ืฉื”ื ืขื ื‘ืŸ ื”ื–ื•ื’ ืฉืœื”ื,
ืื‘ืœ ื‘ืขื™ืงืจ, ื”ืŸ ืชืœื•ื™ื•ืช
14:09
but most importantly, they depend on
284
849014
1725
14:10
how much the husband and wife influence one another.
285
850763
3032
ื‘ื›ืžื” ื”ื‘ืขืœ ื•ื”ืื™ืฉื” ืžืฉืคื™ืขื™ื ืื—ื“ ืขืœ ื”ืฉื ื™.

14:14
Now, I think it's important to point out at this stage,
286
854115
2607
14:16
that these exact equations have also been shown
287
856746

14:20
to be perfectly able at describing
288

what happens between two countries in an arms race.

(ืฆื—ื•ืง)
14:27
(Laughter)
290
867010

So that an arguing couple spiraling into negativity

ืื– ื–ื” -- ื–ื•ื’ ืžืชื•ื•ื›ื— ืฉื ื›ื ืก ืœืกืคื™ืจืœื” ืฉืœ ืฉืœื™ืœื™ื•ืช

14:43
But the really important term in this equation
295
883021
2313
14:45
is the influence that people have on one another,
296
885358

ืขื›ืฉื™ื•, ืกืฃ ื”ืฉืœื™ืœื™ื•ืช,
14:51
Now, the negativity threshold,
298
891158
1732
14:52
you can think of as how annoying the husband can be
299
892914
4627
ืืชื ื™ื›ื•ืœื™ื ืœื—ืฉื•ื‘ ืขืœื™ื• ื›ืžื• ื›ืžื” ืžืฆื™ืง ื”ื‘ืขืœ ื™ื›ื•ืœ ืœื”ื™ื•ืช
